Cured coatings having particles at a surface region of the cured coating are provided. Also provided are multi-component composite coatings which include a cured basecoat deposited from a pigmented coating composition and a cured topcoat deposited from a topcoating composition. The multi-component composite coatings of the invention provide highly scratch resistant color-plus-clearcoatings capable of retaining scratch resistance after weathering.

Cured coatings having improved scratch resistance, coated substrates and methods thereto

The invention pertains to compositions which can be coated onto substrates. These compositions include a combination of a resin blend comprising a first polyester resin and a second polyester resin, wherein the first polyester is different from the second polyester, an aminoplast crosslinking resin, an acid catalyst, and a urea-aldehyde resin. Films prepared from coating compositions made in accordance with the present invention having improved stain resistance. In many instances, films prepared from coating compositions made in accordance with the present invention not only have improved stain resistance, but also have low temperature flexibility.

Coil coating compositions with low temperature flexibility and improved stain resistance

The invention provides a novel coating composition which includes: (a) a polyester-based resin component, (b) an epoxy component, (c) a crosslinker component, (d) a catalyst component, and (e) a diluent component. The polyester-based resin component includes at least one phosphatized polyester resin; and the epoxy component includes at least one phosphatized epoxy resin. These coating compositions are particularly suitable as primers, and especially as primers for use used in conjunction with coating composition which include fluorocarbon polymers. Also provided is a method of providing a substrate with a multilayer coating system. This method includes: (a) applying at least one layer of the aforementioned novel primer onto a substrate; and (b) applying at least one layer of a second coating composition over the primed substrate of step (a). When this method employs the use of a second coating composition which includes fluorocarbon polymers, the results is multi-layered coated substrate which, while having excellent weatherability properties, also has excellent formability properties.
